Method and a system for communication between a terminal and at least one communication equipment
First Claim
1. A method of communicating data securely between a terminal and at least one communicating equipment, which method comprises the steps of:
- setting up at least one connection via at least one connection network between said terminal and said communicating equipment, commanding at least one procedure for activation of said secure communication by at least one first security device installed in said terminal for assigning to management of the secure communication an identifier corresponding to said communicating equipment with which said communication has been set up, said identifier corresponding to said activation procedure, said first security device identifying said communicating equipment in order to recognize the nature of said communicating equipment and to render said communicating equipment compatible with said terminal with no adaptation of the configuration, authenticating said communicating equipment by acquiring data processed by at least one security server using at least one seal key and at least said identifier corresponding to said activation procedure in order to add a random value for said identified communicating equipment, at least one approval device of said security server checking the integrity of said communicating equipment in order to verify if said communicating equipment has been corrupted using at least one integrity checking software executed on said transmitted data at the time of authentication and using random selection from a set of pairs of encryption keys for securing the decryption of said data, comparing the result of decrypting the data processed by said integrity checking software of said security server and executed by said communicating equipment with the result of encrypting the identity of said equipment in said security server, and in the case of identification, authentication and integrity checking results that are all positive and an identity result of said comparison, commanding at least one first management device installed in said terminal to set up secure data communication with said communicating equipment.

Abstract
A method of communicating data securely between a terminal and at least one communicating equipment. The communicating equipment in communication with the terminal is identified by at least one first security device installed in the terminal to recognize the nature of the communicating equipment. The communicating equipment is authenticated by acquiring data processed by at least one security server so that it is executable only by the communications equipment. The integrity of the communicating equipment is checked by at least one approval device of the security server using the data transmitted at the time of the authentication, and, in the event of correct identification, authentication and integrity checking at least one management device installed in the terminal is commanded to set up secure data communication with the communicating equipment.
